I used this deck to climb from unranked, Bronze III, to Masters over the course of two days, roughly 6 hours play time total. Played just a bit over 100 games, averaging ~3 minutes per game, most over in 4-5 turns. The deck performed exceptionally well considering I went into Throne blind, not knowing the meta since I don't play the format normally. The win rate was very high and games only slowed down a little when I reached Diamond I and was getting paired up against higher ranked Masters players.
There are a lot of similarities to other Fire decks currently in Throne, but with a few intentional changes.
Prism Golem felt like it gave me a good advantage against other mono Fire matchups, and Ignite helped keep the board clear for a strong offense. I saw many of the other fire decks out there include Inferno Phoenix, but I opted not to include it because I didn't want to have to hold a 5-cost card and count on drawing power to play it. Another intentional choice was to stick to pure fire sigils, so we'd have high odds of feeding one to Jekk. Star Charts is the only alternate power card because it gives a huge boost when starting second. 4 copies of Scythe Slash, plus Chizue to help push damage through chump blockers.
